The 1995 Argento Viva was the result of work with the Italian design firm Carozzeria Pininfarina. This concept design functioned as a hard top convertible, with a metal roof that could retract into the trunk. The vehicle featured two tones, being constructed of aluminum and fiberglass, and was intended to serve as a high end luxury roadster, with a rear wheel drive, 2.5 Liter 5 cylinder engine.
Honda never moved forward with the production of the Argento Viva, as it was already working on another luxury roadster, the S2000. However, the Argento Viva's story does not end there. The Sultan of Brunei was attracted to the design, and commissioned Pininfarina to deliver a set of four of the vehicles to the Royal Family of Brunei.
To meet this request despite Honda's choosing not to continue development, the Pininfarina Argento Viva instead selected Mercedes to fill in the mechanical components. The vehicle was moved onto the then new Mercedes SL600 chassis, and specced out with AMG components including a 7.3 Liter V12 engine. Fiberglass components were reworked using carbon-fiber, and the interiors were developed using carbon fiber and leather, marrying futuristic design elements with classic luxury comforts.
The resulting design was capable of accelerating from 0 to 60 in under 4 seconds, and capable of a top speed of 175 mph. To fill the royal order, four Pininfarina Argento Vivas were built and delivered at a cost of over 2 million US dollars each. Of these four, two still remain in the possession of the Bruneian royal family. Because the special workshop where these vehicles were built has since closed, it is likely that these unique vehicles will remain one-of-a-kind.
